To calculate the screening constant (σ) for zinc (Zn) for both a 4s-electron and a 3d-electron, we will follow Slater's rules. Here’s a step-by-step solution: ### Step 1: Determine the Electronic Configuration of Zinc Zinc has an atomic number of 30. Therefore, its electronic configuration is: \[ \text{Zn: } 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^{10}, 4s^2 \] ### Step 2: Calculate the Screening Constant for a 4s Electron 1. **Identify the Electrons in the Same Shell (n=4)**: ...
